Minimal resonator loss for circuit quantum electrodynamics
Abstract
Single photon level quality factors of 500x103 are shown in NbTiN superconducting resonators at millikelvin temperatures. This result originates from the intrinsic low dielectric loss of NbTiN, as demonstrated by comparison with Ta, and by removing unnecessary parts of the dielectric substrate.
